How Caliber Engine works with Alpaca
No code required. Three steps to autonomous trading on Alpaca.
Connect your Alpaca account
Link Alpaca through a secure bridge — paper or live. Your funds stay inside Alpaca, your API credentials stay with the bridge provider.
Set capital and limits

Caliber Engine scans, evaluates, sizes, and executes through your Alpaca account autonomously. Every decision logged in your dashboard.
Why Alpaca users choose Caliber Engine
All the API power, none of the code
Alpaca's API is great if you want to write your own strategy. Caliber Engine is for everyone who would rather just have one that works.
Built-in discipline
Same setup criteria, same sizing, same exits — every trade. No emotion, no overtrading, no FOMO.
Free Alpaca paper trading
Connect Alpaca's free paper trading account first. Watch the engine work. Switch to live whenever you are convinced.
Your account stays yours
Caliber Engine never holds your funds. Everything stays inside Alpaca, exactly where it already is.
Built for Alpaca users who do not want to build their own bot
Most people who sign up for Alpaca have one goal: automate their trading. Most of them never finish a working strategy. Building, testing, deploying, monitoring, and improving an algorithmic trading system is a full-time job. Caliber Engine eliminates that work entirely. The engine has the strategy. You connect Alpaca. The engine trades.
Powered by Anthropic Claude, Caliber Engine reads market regime, evaluates probability, sizes positions to a defined risk profile, and manages exits with mechanical discipline. Every outcome is logged. The engine's next decision benefits from the last one. You can start with Alpaca's free paper trading environment to watch it work, then flip to a live account when the results convince you.
Caliber Engine focuses on US equities and ETFs through Alpaca. The engine respects whatever capital limits and risk parameters you configure — no exceptions.
